Section 18 Host Interface X-Bus Interface (XBS)
18.3
XBS has the following registers. XBS registers HICR, IDR_1, IDR_2, ODR_1, ODR_2, STR_1,
and STR_2 can only be accessed when the HIE bit is set to 1 in SYSCR. For details on SYSCR,
refer to section 3.2.2, System Control Register (SYSCR).
18.3.1
SYSCR2 controls the operations of port 6 and host interface.

Description
Key Wakeup Level 1 and 0
Sets the port 6 input level. The input level of port-6
multiplexing pins is also changed by these settings.
00: Port 6 is in the standard input level
01: Port 6 is in input level 1
10: Port 6 is in input level 2
11: Port 6 is in input level 3
Port 6 Input Pull-Up MOS Extra (P6PUE)
Controls and selects the current specification for the
port 6 input pull-up MOS.
0: Standard current specification
1: Current limited specification
Reserved
Only 0 should be written to this bit.
